Methods and apparatus for magnetically coupled hanger and placard for motor vehicles

ABSTRACT

Method and apparatus are disclosed for magnetically connecting a placard to a rearview mirror of a motor vehicle. The apparatus includes a magnetic hanger which connects to the stem of the rearview mirror. A magnetic placard adapter removably receives a hanging portion of a standard placard. The magnetic placard adapter is removably connectable to the magnetic hanger. The magnetic placard adapter is magnetically connected to the magnetic hanger. In other embodiments, the placard itself is formed with a magnetic portion to form a magnetic placard that magnetically couples to the magnetic hanger, directly without the need for the magnetic placard adapter.

FIELD

The embodiments of the invention generally relate to holders for displaying a placard or other printed substrate in the interior of a motor vehicle.

BACKGROUND

Vehicle passes often must be displayed in motor vehicles when the motor vehicle enters or is parked in a restricted area. The vehicle pass oftentimes takes the form of a plastic placard which bears written authorization information. The placard must be displayed in a prominent location so that the operators of the restricted area can view the placard from outside the vehicle. The rearview mirror of the motor vehicle adjacent or coupled to a front window provides a convenient place to attach the placard.

In many instances the placards cannot be permanently mounted to the motor vehicle (e.g. to comply with visibility or other regulations), such when the motor vehicle is operated on the highway, and needs to be dismounted. Between uses, the placard is often stowed away in the glove compartment of the motor vehicle.

Placards are often used by individuals with medical conditions, disabilities, or handicaps to allow them to park in handicap reserved parking spaces adjacent buildings. However, for such individuals, the placards may be difficult to mount and dismount from a rearview mirror due to their condition, disability, or handicap. Accordingly, there is a need to improve placards.
